esp light issues

[darklordmick]

hi all..
i have a 2.2dci santa fe uk spec...and since i have owned it (6months) the esp light keeps coming on...whilst in warranty hyundai replaced brake switch, g lateral sensor and thats about it...its the same fault code every time...lateral G sensor

its been in at least 6 times and still not fixed.....they last blamed my 20" rims and asked if i could get some santa fe 18" alloys....which after much searching the net managed to source at set at great expense...ive just done a full geometry on the car and yet the light still comes on...it goes off for a bit if you turn the engine off and back on again....sometimes anyway...

now out of warranty hyundai are wiping their hands of it...which i feel is unjust as it was not fixed in warranty so as far as im concerned they should still be liable for it...

anyway...does anyone know when the esp light comes on what exactly is the esp controlling/monitoring ...what ever it is the fault is not with the wheels..
i really have had enough of this and now thinking of chopping it in already and get something else...im very disappointed in hyundai's attitude to this fault...

can someone point me in the right direction

its getting more frequent nowadays

by the way...the "esp off" is the only light that shows on my dash board and it doesnt matter what speed im doing, driving in a straight line or turning a corner...yesterday it was on without even moving the car....
this is really doing my head in..
id love to get to the bottom of this...

I had mine go on yesterday for the second time in 3 months... Now it is off. I think I will take it in next week to the dealer.

It seems to be a common thing by the looks of it.. I feel there is too many systems attached to this ESP light...
Let us know what they say on yours.. Be interesting to see if its the same thing as mine... G lateral sensor which has been replaced

If there's ANY issue with the ABS system, like dirty sensors or loose connections, then that will disable the ESP and put the light on.

But wouldn't it show up as a fault code on the ecu.. As far as I know they said its not sensor as no fault code shown..

What's strange and maybe a coincidence, the last few times, it came on within a day or so after a full car wash... Loosen brake dust, dirty sensor? I will let you guys know next week after I take it in.

Just got back from the dealer... They replaced the "stop lamp switch" and updated the ECU...

[darklordmick]

Well I have already has that done.. It was the 1st thing they changed.. Not sure if I have has an ecu update but mine is back at the dealers today and they will check it all out.. I'll let you lot know what they say.. They have had all day today

They only updated the ECU because I asked them to... Did have them change the oil/filter and I had to tighten the cap a little because I noticed a little oil seeping. Whats new. Lol...
